Differential cross sections ${\sigma }_0\left(\theta \right)$ and angular distributions of the vector analyzing power $i{T}_{11}\left(\theta \right)$ have been measured for the processes ${}_{}{}^3{}_{}{}^{}\mathrm{He}$($\overrightarrow{d}$,$d$)${}_{}{}^3{}_{}{}^{}\mathrm{He}$ and ${}_{}{}^3{}_{}{}^{}\mathrm{He}$($\overrightarrow{d}$,$p$)${}_{}{}^4{}_{}{}^{}\mathrm{He}$ from 15 to 40 MeV in intervals of 5 MeV. Data were obtained typically at 25 to 35 angles. In both reactions the angular distributions of the observables, expanded in terms of Legendre polynomials, clearly show structure near 20 and 35 MeV. In addition, an optical model fit to the elastic scattering data was used in an attempt at a distorted-wave Born approximation analysis of the reaction data.
